PROCEEDINGS OF THE SOCIETT. 105 



Mr. Charles T. Druery, F.L.S., President of the Pteridological 

 Society, who has seen my Skipness specimens, says, as his 

 label attached shows — ' This is P. angulare, beyond a doubt, 

 despite the locality.' 



" The only other counties in Scotland from which P. angulare 

 seems to be definitely recorded, and which, with one exception 

 (viz., the first), are given in Professor Trail's Topographical 

 Botany of Scotland, are Kirkcudbright (in the parish of Kells) ; 

 Wigtown; both these as recorded by Mr. James M' Andrew, 

 Roxburgh; and Berwick, at Pease Dean, where Rev. Dr. Paul 

 states it to be abundant; and there is also an old doubted 

 record from Midlothian. 



" In Ireland, which seems to have a congenial soil and 

 atmosphere for the growth of the plant, we find it occurring, 

 according to Prseger's Irish Topographical Botany, in every 

 county, and in England it is also widely distributed, being 

 recorded from Cornwall and Northumberland, and from many 

 intervening counties." 



Reference was then made to the points which distinguish the 

 three species of Shield Fern, P. lonchitis, P. aculeatum, and 

 P. angulare, and the differences between the latter two were 

 briefly diagnosed as follows : — 



P. aculeatum — glossy in appearance: rigid in texture: pin- 

 nules wedge-shaped, almost sessile: the pinnae diminishing 

 gradually downwards. P. angulare — lax, drooping: the teeth of 

 the leaves long-awned: the base of the pinnules obtuse, and 

 shortly but distinctly stalked. 



Mrs. Peter Ewing exhibited Juncus tenuis, Willd., from Argyll- 

 shire, and read a paper giving some interesting details regarding 

 the distribution of the plant (see page 22). 



Dr. Robert Brown exhibited a collection of Swiss Alpine 

 Plants, amongst them being several specimens of the Swiss 

 Carex frigida, AH., from different altitudes, on which he contri- 

 buted a short paper. He stated that this Carex is very plenti- 

 ful in the Swiss mountains, and is found in greatest profusion 

 and perfection about 6,000 feet up. It is generally growing on 

 the banks of running streams, or on the soft wet slopes, where 

 the roots have freedom to sink and spread. Very often it is 

 found in the company of Carex atrata. When by the running
